Application in practice and solution to integer cycle ambiguity of RTK in fast speed

分析了GPS-RTK测量速度的关键即解算整周模糊度,通过对RTK整周模糊度算法原理的分析,提出了快速RTK求解整周模糊度算法。该算法首先确定未知点的初始坐标,进而得到初始模糊度;然后以初始值为中心建立一个搜索空间,应用最小二乘原理搜索出准确的模糊度值。

The critical problem about GPSRTK-solution to the integer cycle ambiguity was analyzed. By analyzing its principle, how the integer cycle ambiguity of RTK was calculated in fast speed. In this method of solution, the initial point' s coordinate can be determined in the primary step in order to get the initial ambiguity, and then construct a finding space with initial value as centre and obtain an accurate ambiguity value by least square method.
